The insulator string connector for the transmission line has the advantages that insulator strings on the transmission line can be prevented from being bridged by icicles, the creepage distance and the dry arcing distance are increased, and an icing power frequency flashover voltage, a pollution power frequency flashover voltage and a lightning impulse discharge voltage are improved; a tower top can be prevented from rain flashover; bird manure pollution flashover is avoided; a lightning flashover voltage can be improved; and the pole and tower window size can be reduced, and a line corridor can be omitted, so that the investment can be saved.
Description
Technical field
The utility model belongs to the electric power project engineering field, relates in particular to a kind of electric transmission line isolator string connector.
Background technology
Be subjected to the influence of insulator string creepage distance and dry arcing distance deficiency, when mal-conditions such as meeting with icing, filth or damage to crops caused by thunder influences, the discharge voltage of these insulator strings reduces greatly, in recent years, again and again take place because of icing, damage to crops caused by thunder cause electric transmission line isolator string flashover fault, had a strong impact on the safe operation of electrical network and the people's normal life.Therefore, increase the creepage distance and the dry arcing distance of insulator string,, guarantee that the safe operation of transmission line is very necessary improving covering ice for insulator power frequency flashover voltage, filthy power frequency flashover voltage and lightning impulse discharge voltage.Yet numerous old transmission lines all are the conservative design that adopts economizing type at present, are subjected to the restriction of tower head size and distance to the ground, and directly insulator sheet number is regulated creep distance and dry arcing distance is very difficult by increasing.
The utility model content
The technical problems to be solved in the utility model is, defective at the known technology existence, a kind of electric transmission line isolator string connector that prevents insulator full skirt edge sleet bridge joint, improves icing power frequency flashover voltage, the filthy power frequency flashover voltage of raising and lightning impulse discharge voltage is provided, use this connector to arrange insulator, can transform the tangent tower of existing tower head size and distance to the ground deficiency, improve the transmission line power supply reliability, reduce investment outlay.
Technical solution of the present utility model is that referring to accompanying drawing 1, the electric transmission line isolator string connector that is provided has a fan-shaped yoke plate 2 and three links 1 as shown in Figure 1.The top, obtuse angle of wherein said fan-shaped yoke plate 2 and covering of the fan camber line are respectively equipped with circular hole 21 along the limit.Wherein be located at described fan-shaped yoke plate 2 covering of the fan camber lines and be radial equally distributed circular holes for a plurality of along the circular hole 21 on limit.Two links 1 in described three links 1 are hung on the circular hole 21 at described fan-shaped yoke plate 2 covering of the fan camber line two ends by bolt respectively.The other end that these two links 1 connect described fan-shaped yoke plate 2 one ends respectively is connected to a ball-eye 3.Surplus a link 1 and be hung on the circular hole 21 on the top, obtuse angle that is positioned at described fan-shaped yoke plate 2 by bolt.The other end that the surplus link 1 of this institute connects described fan-shaped yoke plate 2 one ends is connected to a socket-clevis eye 4.When the electric transmission line isolator string connector of the present utility model that constitutes thus uses, this socket-clevis eye 4 with surplus link 1 other end that is connected an end be insulator string 5 on the outer end connection peripheral hardware transmission line; And described ball-eye 3 is the outer end with the other end that described two links 1 are connected an end respectively, also connects the insulator string 5 on the peripheral hardware transmission line when electric transmission line isolator string connector of the present utility model uses respectively.
Operation principle of the present utility model is: connect fan-shaped yoke plate 2 and socket-clevis eye 4 by above-mentioned link 1; Fan-shaped yoke plate 2 is connected the straight line insulator string string 5 that dangles on the transmission line by top link 1 with socket-clevis eye 4, fan-shaped yoke plate 2 lower edges connect circular hole 21 and are connected both sides horizontal linear insulator string string with ball-eye 3 by link 1.And then by changing the sag of link 1 at the link position adjusting both sides at fan-shaped yoke plate 2 edges transmission line wire.Utilize insulator string on this transmission line to fall " T " font and arrange connector, the straight line falsification of dangling that will regulate creepage distance and increase the dry arcing distance difficulty is for falling " T " font strain insulator straight line string.Not needing to change tower head and changing under the situation of distance to the ground, improve the creepage distance and the dry arcing distance of insulator string greatly, and then realize improving the purpose of insulator string external insulation level; In addition, utilize this electric transmission line isolator string to fall " T " font and arrange that connecting gold utensil will dangle the straight line falsification for falling " T " font strain insulator straight line string, can effectively prevent icing insulator in season full skirt, improve the anti-ice level of insulator string by the ice slush bridge joint.
The beneficial effects of the utility model are:
1), can avoid insulator string on the transmission line by the sleet bridge joint, increase creepage distance and dry arcing distance, improve icing power frequency flashover voltage, improve filthy power frequency flashover voltage and lightning impulse discharge voltage;
2), can avoid the cat head filthy formation curtain of rain and the rain sudden strain of a muscle takes place;
3), can avoid forming the birds droppings pollution flashover;
4), can improve lightning stroke flashover voltage;
5), can reduce shaft tower window size and circuit corridor, the saving investment.
